Dianne pays $28 just to get in, no matter how many rides she rides. however, the cost of her total rides depends on how many rides she goes on.
the equation that can be used to represent this is
c = 2x + 28
her total cost will be $28 plus the total cost from the rides she went on and since we don't know how many that is, we add x.
hope this helped!
Answer:
Every week, the radioactivity decreases by a factor of 5
After 1 week, it goes from 5,000 to 1,000
2 weeks 1,000 / 5 =200
3 weeks 200 / 5 = 40
4 weeks 40 / 5 = 8
5 weeks 8 / 5 = 1.6
6 weeks 1.6 / 5 = 0.064
7 weeks 0.064 / 5 = 0.0128
8 weeks .0128 / 5 = 0.00256
9 weeks 0.00256 / 5 = 0.000512
10 weeks 0.000512 / 5 = 0.0001024
Step-by-step explanation:
X=-11/3 This is the answer to your problem
No. Area of a circle equals pi times the radius squared. That means multiply the radius times itself. For example, if the radius is 3, the area = π x 3 x 3 = 9π
1). 3X+6=75
75-6=69=23
